Dear Natasha,
RE Your report: Research suggests biological base for ADHD
We watched with interest this report
which was broadcast on the evening of December 3rd 2007. Unfortunately we
felt it made a number of mistakes that are commonly found in reports
of 'new' research into the diagnosis of Attention Deficit
Hyperactivity Disorder (ADHD).
Firstly your report did not mention
whether the researchers interviewed had published the results of
their study in a peer reviewed journal. The information available on
the website of the Academic Child Psychiatry Unit at the Royal
Children's Hospital in Melbourne would suggest that the research
project is not yet complete. Therefore we presume that the
researchers have not yet subjected their findings to a process of
peer review. It would have been useful if you had provided this
information in your report so that viewers were aware that the
research and the results had yet to face the scrutiny of the
scientific community. This is especially important given the
controversy of the ADHD diagnosis.
Your report also did not disclose any
professional affiliations the researchers may have had or the sources
of funding for the research. This is important information as it can
help the viewer to exclude the possibility of bias when listening to
the researchers claims.
More importantly, the report showed no
evidence of background research into the many serious criticisms that have been levelled
against research claiming a biological basis for 'ADHD' from
the medical and human service professions. A number of
peer reviewed journal articles in the medical literature have exposed
the fact that claims for a biological basis of ADHD rest on a house
of cards. Indeed, all research to date that claims a biological
basis for the condition have serious and damning flaws. The main
criticisms of the research are that:
-
to date the vast bulk of research
has failed to control for the effect of prior exposure to drugs;
-
On the few occasions when
researchers have included non-medicated children diagnosed with ADHD
in their experiments they have either:
-
failed to compare them to
controls appropriately matched for their age,weight and height; or
-
failed to make the comparison at
all between the un-medicated 'patient' group and the control group.
It was impossible to ascertain from your report whether this this 'world first' research had managed to overcome the mistakes of previous studies. We can only guess that the answer is no - one thing that was
clear from your report is that at least two of the subjects in the
research did have significant prior exposure to drugs.
So the question remains - are the differences the researchers claim to have identified a result of prior exposure to drugs, or was the difference there already?
You can find a selection of
peer-reviewed journal articles and other literature that outline
these problems on the website of the Youth Affairs Network of
Queensland at:
http://www.yanq.org.au/content/view/521/71/1/5/.
As you stated yourself, ADHD is a
controversial condition. It's controversy stems largely from the
unfounded claims of dozens of researchers that 'ADHD' has some sort
of biological basis. In future, some simple questions may help to verify the quality of researchers claims before they go to air:
-
Has the research report provided
details of the medication history of its subjects?
-
If yes, do the authors discuss the
effects the medication will have on their subjects and the
implications for their findings?
-
Has the research compared similar
subjects? For example, is the control group of similar age, weight
and sex to the experimental group?
-
Have the researchers disclosed any
affiliations to companies or organisations that may have an interest
in ADHD medication?
-
Have the researchers provided
information about the funding body (or bodies) behind the research,
and any relevant affiliations these organisations have?
The endless search to find something
'wrong' within children that are different is an expensive and
pointless exercise. Besides providing a baseless rationale for the
manufacture and sale of expensive drugs to control children and young
people, it diverts our attention from finding ways to celebrate all
sorts of children - whether they are hyperactive or quiet,
inattentive or highly focused.
Interestingly, your report claimed that
children diagnosed with 'ADHD' can function 'normally' except in high
stress environments. The accompanying visuals suggested that schools
can indeed be high stress environments. Given that billions of
dollars and decades have already been spent looking for the elusive
biological basis of 'ADHD' we ask if it is time for a change.
Perhaps children and young people would be better served if we
diverted our time and energy elsewhere. For example, creating
low-stress schools and other institutions for children and young
people that celebrate their differences and focus on their strengths.
Yours
sincerely
